A composition including a solid substrate, a metal chelant, and a saturated hydrocarbon linker attached between the substrate and the chelant, wherein the chelant is an organic wherein the chelant is an organic macrocycle or polyol.

Metal complexing

Multifunctional chelating groups are covalently bound to acrylate or methylate monomers. These monomers are polymerized. The resulting polymers are highly substituted with chelating groups and are useful for removing metals from fluids such as liquid hydrocarbons. An example of a polymer according to this invention has the following structure: ##STR1## wherein Q is a saturated or unsaturated aliphatic group having 1 to about 200 carbon atoms and is typically an unsubstituted unbranched alkylene, a substituted unbranched alkylene, a substituted branched alkylene, or an unsubstituted branched alkylene, and is an integer having a value of at least 1.

Synthesis of acrylate and alkyl acrylate monomers and polymers of

A composition including a solid substrate, a metal chelant, and a saturated hydrocarbon linker attached between the substrate and the chelant. The position is used in the method for removing from a liquid medium a metal having atomic number equal to or greater than 27, the method including the steps of passing the liquid medium through the composition that is in solid, particulate form and separating the medium from the composition.
